for a 7900 gtx card some people tell me i should have more power and some people say no looking for your take thanks also her are my clock speed what should i make faster for gaming cpu 2395.75 fsb 199.65 ram 199.63 two gig pcie 101.75 pci 33.92
thanks for the help


+5v,+12v1,+12v2,and+3.3vmax.load 390 watts
+5vand3.3vmax.output 130 watts
ac input 8a/115v,5a/230v;60 50 hz

its a antec 2.0 smart choice dual fan atx 12 v

do you think i should have more power i dont want to hurt the card or cpu

We're talking 25A total on the 12V rails... (10A on 12V1 and 15A on 12V2). Given the other specs (390W on all siginificant rails, and 130W on the 3.3V and 5V rails), I am assuming that the 25A is the actual max load on the 12V rails (can't verify this on Antec's website).

If you want to overclock, you want to increase your FSB, and thus your CPU frequency. RAM speed will also increase, and if you encounter instabilities, you can knock it down a bit again. Leave the PCI-E and PCI bus are they are!!

Also, you can overclock your video card separately, using a program like rivatuner (I believe that's it for nVidia cards).

However, if you start overclocking, the PSU might be a bit too light.... for stock it's fine, for overclocking, you might hit the limits.

At stock, we're looking roughly at this kinds of power requirements (mostly on the 12V rails...)
- CPU: 89W (~7.5A)
- RAM: 14W (~1A - not on the 12V rail)
- Video: 84W (7A)
- HDD: 18W (~1.5A - not all on the 12V rail... let's assume 1A on 12V rail)
- Mobo: 40W (~ 3.5A - not all on the 12V rail... let's assume 3A on the 12V rail)

Let's assume another 5A for optical drive(s), fans, etc, etc.

Total load on the 12V rail: 24.5A at stock, assuming that everything is fully loaded at the same time.

Thus, it'll run your rig at stock, but no headroom whatsoever.

Think about replacing if you want to overclock.

I would get a new psu like chozart said if you want to overclock (who wouldnt) if you feel like you want to replace one give a budget and I garuntee me and chozart could find you a better psu to replace that

I would upgrade to at least a XCilo GoodPower 500W, $52@new egg.
